Change test files to be .luau

[Baileyeatspizza]

as the file extension .luau is now supported it only seems fitting to change the test files to reflect that

I did a quick test and this seems to work fine

please ignore the error it was reported in #171 but it shows that the file that errored is in fact luau 🥳

if you think I changed some code where I shouldn't have please suggest a change or if you have write access just remove it!

this change isn't exactly necessary but it helps to start building an ecosystem of .luau soon we could replace every .lua file in this repository with .luau

This shouldn't be a quick change please take time to ensure everything is working properly.

As mentioned on the relevant issue, we should take small steps to adopt the new extension. Right now merging this will mean that we lose syntax highlighting, language attribution on GitHub, quality of editor integration in various editors, etc., for all of these files.

Please be patient; we can take a look at renaming the internal files to use .luau extension once these change, but I don't think it's the right time yet.

ah I understand

I'm going to close this for now. We may come back to this in the future, but for now this change would result in some issues on our end and may get difficult to merge across the two repositories so it would be better if we handled this internally.

Heya, I believe it is possible to include syntax highlighting for a language on GitHub, by simply contributing to GitHub's syntax highlighting library, "linguist".

That would be nice to add.
I'm not ready to make it myself right now (even though I have experience in TextMate grammars), so maybe some next time or someone else in the team/community.

Was figuring the same, I personally do not have much experience here, but I'll go looking for possible contributors within the Roblox OSS Community.

An update on this, I think I'll be able to implement it myself, seems pretty trivial... But before I do so, I'd need to know:

1. What the preferred color for the language would be? (#00a2ff, perhaps?)
2. As for the group parameter, is luau considered a child language of lua?

# group                 - Name of the parent language. Languages in a group are counted
#                         in the statistics as the parent language.

Lastly, we would need to add luau's grammar to ace, which is the syntax highlighting library that linguist uses.

UPDATE: This would have to be put on hold for the timebeing as it looks like GitHub has temporarily changed the language criteria for eligible languages.
